Subject: [PATCH v3 02/10] arm: dts: renesas: r8a7740: Add clocks for FSI
Date: Sun, 10 May 2026 15:42:55 +0700	[thread overview]
Message-ID: <20260510084303.122426-3-phucduc.bui@gmail.com> (raw)
In-Reply-To: <20260510084303.122426-1-phucduc.bui@gmail.com>

From: bui duc phuc <phucduc.bui@gmail.com>

Add the SPU clock to the FSI node to ensure it is enabled before register
access, preventing potential system hangs.
Add missing clocks for FSI (icka/b, xcka/b).
